ABSTRACT

Astragali Radix (A. Radix) is the dried root of Astragalus membranaceus var. mongholicus (Bge) Hsiao or Astragalus membranaceus (Fisch.) Bge., belonging to the family Leguminosae, which is mainly distributed in China. A. Radix has been consumed as a tonic in China for more than 2000 years because of its medicinal effects of invigorating the spleen and replenishing qi. Currently, more than 400 natural compounds have been isolated and identified from A. Radix, mainly including saponins, flavonoids, phenylpropanoids, alkaloids, and others. Modern pharmacological studies have shown that A. Radix has anti-tumor, anti-inflammatory, immunomodulatory, anti-atherosclerotic, cardioprotective, anti-hypertensive, and anti-aging effects. It has been clinically used in the treatment of tumors, cardiovascular diseases, and cerebrovascular complications associated with diabetes with few side effects and high safety. This paper reviewed the progress of research on its chemical constituents, pharmacological effects, clinical applications, developing applications, and toxicology, which provides a basis for the better development and utilization of A. Radix.

ABSTRACT

Numerous flavonoid Diels-Alder-type natural products have been isolated and received great attention from the synthetic community. Herein, we reported a catalytic strategy for an asymmetric Diels-Alder reaction of 2'-hydroxychalcone with a range of diene substrates using a chiral ligand-boron Lewis acid complex. This method enables the convenient synthesis of a wide range of cyclohexene skeletons in excellent yields with moderate to good enantioselectivities, which is critical to prepare natural product congeners for further biological studies.

ABSTRACT

OBJECTIVES@#To study the value of basal luteinizing hormone (LH) level combined with uterine volume measurement in the early diagnosis of central precocious puberty (CPP) in girls with different Tanner stages.@*METHODS@#A retrospective analysis was performed on the girls who presented with breast development before the age of 8 years and attended the Third Affiliated Hospital of Zhengzhou University from January 2017 to September 2022. According to the results of gonadotropin-releasing hormone (GnRH) agonist test, the girls with peak LH ≥5.0 IU/L and peak LH/follicle stimulating hormone ≥0.6 were enrolled as the positive group, and the other girls were enrolled as the negative group. The two groups were compared in terms of the basal LH level and uterine volume. The receiver operating characteristic (ROC) curve was used to analyze their value in the early diagnosis of CPP.@*RESULTS@#For the girls with Tanner B2 and B3 stages, the positive group had significantly higher basal LH level and uterine volume than the negative group (P<0.05). The basal LH level had an optimal cut-off value of 0.325 IU/L and 0.505 IU/L respectively in the diagnosis of Tanner stage B2/B3 CPP, while uterine volume had an optimal cut-off value of 1.639 mL and 2.158 mL respectively. Basal LH level combined with uterine volume measurement had a significantly larger area under the ROC curve than uterine volume measurement alone (P<0.001), but with no significant difference compared with that of basal LH level measurement alone (P>0.05).@*CONCLUSIONS@#Basal LH level combined with uterine volume measurement is valuable in the early diagnosis of CPP in girls with different Tanner stages, which provides a basis and guiding significance for clinical diagnosis of CPP.

ABSTRACT

Background: It is generally believed that sedentary behavior (SB) increases the risk of falls among older adults, but the evidence for it remains inconsistent and scarce. Purpose: Our study aims to provide a systematic review and meta-analysis of available evidence regarding the association of SB with falls in older adults. Method: A comprehensive search strategy was conducted using several online databases from 1906 to March 2022. Cohort studies both concerning the association between SB and falls and involving participants over 60 years old were regarded as eligible for inclusion. Evidence was pooled by a random-effects meta-analysis. Quality assessment for individual studies was performed with the Newcastle-Ottawa Scale (NOS). Results: Altogether seven publications were identified, and the age of the 24,750 individuals involved ranging from 60 to 99 years old. Overall quality of the included studies was rated as moderate-to-high quality. We found that SB was significantly associated with increased risk of falls compared with non-SB among older adults [Odds ratio (OR) = 1.17, 95% confidence interval (CI): 1.07-1.28; I 2 = 46.90%, P heterogeneity = 0.07, random model]. Subgroup analyses that stratified the studies according to NOS score showed significant differences between groups. Subgroup analysis stratified by SB measurement, sample size, region, publication year, and follow-up duration showed no significant differences between groups. Conclusion: The findings provide reliable support for the hypothesis that sedentary lifestyles are strong predictors of falls among older adults, offering critical indications to develop strategies for fall prevention.

ABSTRACT

ObjectiveTo observe the effects of Bufei Yishen prescription on airway mucus hypersecretion and Notch signaling pathway related protein Notch3 and enhancer of split homologue 1 (HES1) in rats with chronic obstructive pulmonary disease (COPD) and to explore its action mechanism. MethodForty-eight SD rats were randomly divided into the control group, model group, Bufei Yishen prescription group, and aminophylline (APL) group,with 12 rats in each group. The stable COPD rat model was established via cigarette smoking exposure combined with Klebsiella bacterial infection for 12 weeks, and the corresponding drugs (3.7 g·kg-1·d-1 Bufei Yishen prescription and 54 mg·kg-1·d-1 APL) were administered by gavage during the next eight weeks. After the last administration at week 20, the lung tissue was sampled for observing the pathological changes and the rat lung function was detected. The tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and mucoprotein 5AC (MUC5AC) in bronchial alveolar lavage fluid and the mRNA and protein expression levels of Notch3, HES1, and MUC5AC in lung tissues were assayed. ResultCompared with the control group, the model group exhibited significantly weakened pulmonary function (P<0.05,P<0.01), reduced average number of alveoli (P<0.01), elevated mean linear intercept (P<0.01), and up-regulated TNF-α, IL-6, and MUC5AC in bronchial alveolar lavage fluid and Notch3, HES1, and MUC5AC mRNA and protein expression in lung tissue (P<0.05,P<0.01). Compared with the model group, Bufei Yishen prescription and APL remarkably enhanced pulmonary function, alleviated its pathological injury (P<0.05,P<0.01), and down-regulated TNF-α, IL-6, and MUC5AC in bronchial alveolar lavage fluid and the mRNA and protein expression levels of Notch3, HES1, and MUC5AC in lung tissues (P<0.05,P<0.01). ConclusionThe mechanism of Bufei Yishen prescription in inhibiting airway mucus hypersecretion of COPD rats was related to its regulation of Notch3 and HES1.

ABSTRACT

In this paper, we investigate the relationship between the air pollution and tuberculosis cases and its prediction in Jiangsu, China by using the time-series analysis method, and find that the seasonal ARIMA(1, 1, 0)×(0, 1, 1)12 model is the preferred model for predicting the TB cases in Jiangsu, China. Furthermore, we evaluate the relationship between AQI, PM2.5, PM10 and the number of TB cases, and find that the prediction accuracy of the ARIMA model is improved by adding monthly PM2.5 with 0-month lag as an external variable, i.e., ARIMA(1, 1, 0)×(0, 1, 1)12+PM2.5. The results show that ARIMAX model can be a useful tool for predicting TB cases in Jiangsu, China, and it can provide a scientific basis for the prevention and treatment of TB.

ABSTRACT

Objective:To investigate the relationship of single nucleotide polymorphism (SNP) of high mobi-lity group protein A2 ( HMGA2) gene with prepubertal idiopathic short stature (ISS) and the efficacy of recombinant human growth hormone (rhGH) in Han population of Henan Province. Methods:A total of 120 children who were diagnosed with prepubertal ISS and treated with rhGH standards for at least one year from July 2017 to September 2019 at the Children′s Endocrinology Clinic of the Third Affiliated Hospital of Zhengzhou University were enrolled in the ISS group of this study.Meanwhile, 120 healthy children (control group) of the same age and gender whose height was within the normal range were selected as controls.Their peripheral blood was collected, and the polymorphism distributions of SNP loci(rs1042725 and rs7968682)were determined by molecular biology.Analysis was carried out to specify the annual growth rate, height standard deviation score (HtSDS), and insulin-like growth factor-1(IGF-1) of ISS children with different genotypes (before and after treatment )and those in the control group.Results:(1)In both ISS group and control group, children with CC and CT alleles at rs1042725 locus of HMGA2 had higher growth rate than those with TT allele before treatment[(4.33±0.64) cm/year, (3.95±0.45) cm/year; (6.35±0.41) cm/year, (6.12±0.32) cm/year vs.(3.76±0.52) cm/year, (5.96±0.42) cm/ year], therefore the difference were statistically significant (all P<0.05). (2)After treatment with GT genotype at the HMGA2 rs7968682 locus in children with ISS, the growth rate of age and bone HtSDS was higher than that of TT genotype [(0.74±0.30) cm/year vs. (0.63±0.24) cm/year, (0.16±0.05) cm/year vs.(0.14±0.05) cm/year], therefore the differences were statistically significant(all P<0.05). Conclusions:The polymorphism of the HMGA2 SNP locus (rs1042725) in the Han population of Henan province may be related to ISS level, while the polymorphism of the SNP locus (rs7968682) may be related to rhGH efficacy.

ABSTRACT

The complete sequence of the mitochondrial genome of Podagrion sp. (Hymenoptera: Torymidae) is described. The mitogenome was 15,845 bp in size, and contained typical sets of mitochondrial genes. The base composition of the Podagrion sp. mitogenome was also biased toward A + T bases (81.8%). The mitochondrial genome of Podagrion sp. has a weak AT skew (0.07) and a strong GC skew (-0.26). Podagrion sp. exhibits a novel rearrangement compared with the ancestral order, including six protein-coding genes (nad3, cox3, atp6, atp8, cox2 and cox1), which have inverted to the minor strand from the major strand. The A + T-rich region of Podagrion sp., which is located between trnN and trnI, have five tandem repeats. The apomorphic rearrangements, including the conserved block "cox3-atp6-atp8-cox2-cox1-nad5-nad4-nad4l-nad6-cob" and the special locations of trnV and trnA, were mapped onto the phylogeny of Proctotrupomorpha.

ABSTRACT

This study based on~1H-NMR urine metabolomics technique combined with biochemical indicators to focus on studying the acute hepatotoxicity mechanism of Artemisia argyi essential oil( AAEO). In order to further explore the acute hepatotoxicity mechanism of AAEO,the researchers collected the urine nuclear magnetic data of rats in different periods of high and low doses of olive oil and AAEO group. Using the principal component analysis( PCA) and orthogonal partial least squares-discrimination analysis( OPLSDA) to analyze the endogenous small molecule metabolites in rat urine to study the effects of AAEO on the metabolic process of normal rats. The results showed there was a significant difference between the olive oil group and the AAEO group,the PCA scores chart demonstrated that there was no obvious separation tendency in the urine of olive oil group rats 0-6,6-12,12-24 h,and the metabolic components were distributed in aggregation pattern. The urinary metabolic trajectory of the rats in the AAEO group was conspicuously separated at 0-6,6-12,12-24 h. The experiments proved that the analysis of metabolites by~1H-NMR found that AAEO caused metabolic disorders in rats and produced acute hepatotoxicity. After metabolite differential comparison,it was speculated that the mechanism of acute hepatotoxicity may be involved in the tricarboxylic acid cycle and energy metabolism,while the citrate and oleanolic acid would be the potential biomarkers. This study discussed that the acute hepatotoxicity mechanism of AAEO was used to provide the experimental data for the clinical prescription of Artemisia argyi.

ABSTRACT

PURPOSE: To evaluate the quality of life among survivors after sepsis in 2 years, comparing with critical patients without sepsis and the general people, analyze the changes and the predictors of quality of life among septic survivors. METHODS: This prospective case-control study screened the intensive care unit (ICU) patients in Tianjin Third Central Hospital from January 2014 to October 2017, and the Chinese general population in the previous studies was also included. According to inclusion criteria and exclusion criteria, 306 patients with sepsis were enrolled as the observation group, and another 306 patients without sepsis in ICU during the same period, whose ages, gender and Charlson Comorbidity Index matched with observation group, were enrolled as the control group. At 3 mo, 12 mo, and 24 mo after discharge, the Mos 36-item Short Form Health Survey (SF-36), the Euroqol-5 dimension (EQ-5D), and the activities of daily living (ADL) were evaluated in face-to-face for the quality of life among survivors. RESULTS: There were 210 (68.6%) septic patients and 236 (77.1%) non-septic critically ill patients surviving. At 3 months after discharge, the observation and control groups had the similar demographic characteristics (age: 58.8 ± 18.1years vs. 57.5 ± 17.6 years, p = 0.542; male: 52.0% vs. 51.4%, p = 0.926). However, the observation group had higher acute physiology and chronic health evaluation II (APACHEII) scores, higher sequential organ failure assessment (SOFA) scores, longer hospital stay, and longer ICU stay than the control group did (p < 0.05). There were no significant differences in the eight dimensions of the SF36 scale, the EQ-5D health utility scores, and the activities of daily life scores between septic survivors and non-septic survivors (p > 0.05). In addition, compared with the quality of life of the Chinese general population (aged 55-64 years), the quality of life of septic patients were significantly lower at 3 months after discharge (p < 0.05). Comparing the quality of life of the ill patients who had been discharged at 3 mo and 24 mo, the general health improved statistically (p = 0.000) and clinically (score improvement > 5 points). Older age (OR, 1.050; 95% CI, 1.022-1.078, p = 0.000), female (OR, 3.375; 95% CI, 1.434-7.941, p = 0.005) and longer mechanical ventilation time (OR, 3.412; 95% CI, 1.413, 8.244, p = 0.006) were the risk factors for the quality of life of septic survivors. CONCLUSION: The long-term quality of life of septic survivors was similar to that of non-sepsis critically ill survivors. After discharge, the general health of sepsis improved overtime. Age, female and mechanical ventilation time (>5 days) were the predictors of the quality of life after sepsis.

ABSTRACT

Sixty novel allogibberic acid derivatives containing 1,2,3-triazole pharmacophore were designed and synthesized. The key chemical processes include aromatization of the A ring in gibberellins, formation of allogibberic azides and its copper mediated Huisgen 1,3-dipolar cycloaddition with alkynes. A number of hybrids containing α,ß-unsaturated ketone moiety exhibited excellent in vitro cytotoxic activities. Some of the hybrids were more selective to MCF-7 and SW480 cell lines with IC50 values at least 8-fold more cytotoxic than cisplatin (DDP). The most potent compounds C43 and C45 are more cytotoxic than cisplatin (DDP) against all tested five tumor cell lines, with IC50 values of 0.25-1.72 µM. Mechanism of action studies indicated that allogibberic-triazole derivative C45 could induce the S phase cell cycle arrest and apoptosis in SMMC-7721 cell lines.

ABSTRACT

BACKGROUND: Long noncoding RNAs (lncRNAs) are a new class of cancer regulators. Here, we aimed to investigate the diagnostic and therapeutic values of an lncRNA, differentiation antagonizing noncoding RNA (DANCR), in lung cancer. METHODS: Real-time polymerase chain reaction was used to compare DANCR levels in normal and cancerous lung tissues as well as lung cancer cells. Lentiviral transduction was used to induce DANCR overexpression or silencing in vitro, followed by monitoring cell proliferation, colony formation, and changes in microRNA-216a (miR-216a) expression. DANCR-specific small hairpin RNA transduction was used to establish cells with stable DANCR knockdown, and silenced cells were used to initiate lung tumor xenografts, followed by monitoring tumor growth. RESULTS: DANCR upregulation was seen in lung cancer, particularly in high-grade lung cancer tissues and aggressive cancer cells. Ectopic DANCR expression induced lung cancer cell proliferation and colony formation, whereas DANCR silencing induced opposing effects. The miR-216a level in cancer cells was negatively correlated with DANCR expression. The DANCR knockdown reduced the growth of tumor xenografts in vivo. CONCLUSION: DANCR upregulation is a potential indicator of aggressive lung cancer. Silencing of DANCR has great potential as a potent therapeutic strategy in lung cancer.

ABSTRACT

Oesophageal cancer (OC) is one of the most fatal malignancies in the world, and chemoresistance restricts the therapeutic outcome of OC. Long noncoding RNA (lncRNA) was reported to play roles in multiple cancer types. Yet, the function of lncRNA in chemoresistance of OC has not been reported. A lncRNA gene, PCAT-1, showed higher expression in OC tissues, especially higher in secondary OC compared with normal mucosa tissues. Overexpression of PCAT-1 increased the proliferation rate and growth of OC cells. Inhibition of PCAT-1 decreased proliferation and growth of OC cells, and increased cisplatin chemosensitivity. In a mouse OC xenograft model, PCAT-1 inhibition repressed OC growth in vivo. Therefore, PCAT-1 may potentially serve as a therapeutic target for treating OC. PCAT-1 promotes development of OC and represses the chemoresistance of OC to cisplatin, and silencing of PCAT-1 may be a therapeutic strategy for treating OC.

Older age (OR, 1.050; 95% CI, 1.022-1.078, p = 0.000), female (OR, 3.375; 95% CI, 1.434-7.941, p = 0.005) and longer mechanical ventilation time (OR, 3.412; 95% CI, 1.413, 8.244, p = 0.006) were the risk factors for the quality of life of septic survivors.</p><p><b>CONCLUSION</b>The long-term quality of life of septic survivors was similar to that of non-sepsis critically ill survivors.

ABSTRACT

Beetles in the weevil subfamily Platypodinae are among the dominant groups of insects in wet tropical forests, which together with bark and ambrosia beetles in the subfamily Scolytinae. Easily recognised by the circle-shaped entrance holes in fallen logs and a very elongated body shape, they have earned the common name, "pinhole borers". All except two Platypodinae species are ambrosia beetles that cultivate fungi in wood tunnels as the sole food for their larvae. Platypodinae is a peculiar weevil subfamily of species that cultivate fungi in tunnels excavated in dead wood. The Platypodinae is likely the oldest known lineage of fungus-cultivating insects, with an origin of the ambrosial habit more than 80 Ma. Here, we sequenced and characterized the complete mitochondrial genome of E. parallelus, which was collected from logs imported from SierraLeone. The complete circular mitochondrial genome (mitogenome) of Euplatypus parallelus is 16,095 bp in size, containing 37 typical genes and one non-coding AT-rich region. The AT content of the AT-rich region is 87.5%. All protein-coding genes (PCGs) start with standard ATN initiation codons except for nad1and end with complete termination codons TAA except for cox1genes using an incomplete stop codon T. tRNA genes are predicted with a characteristic cloverleaf secondary structure except for trnS1(AGN) , whose dihydrouridine (DHU) arm is replaced by a simple loop. The size of the large and small ribosomal RNA genes are 1386 and 741 bp, respectively.
